  1. Warm-Up… • Identify the values for a, b, and c using f(x) = ax2 + bx + c if f(x) = x2 – 2x – 2 • Quickwrite… • What are the pros and cons (benefits and disadvantages) of being in your grade? Explain. • Ex: “The pros and cons of being in ___th grade are___________ because ____________________.” Tutoring Today!

  2. starting with Student #3 • Identify the values for a, b, and c using f(x) = ax2 + bx + c if f(x) = x2 – 2x – 2 Compare & Explain…

  3. starting with the student who went to bed the latest in your group (1 min) • What are the pros and cons (benefits and disadvantages) of being in your grade? Explain. • Ex: “The pros and cons of being in ___th grade are___________ because ____________________.” Round Robin…

  4. Graphing Quadratic Functions in Standard Form

  5. What is the Standard Form?

  6. a has the same meaning in the vertex and standard form • The axis of symmetry can be found at x = - • c is the y-intercept, so it can be found at (0, c) What do a, b, and c tell us?

  7. Graphs Using Standard Form

  8. Example

  9. Graph the function. Label the vertex and axis of symmetry. Practice
